Product Description:

The PMB33F-10200-03 is a brushless servomotor produced by Pacific Scientific as part of the PMB Brushless Servomotors series. The unit is designed to supply controlled rotary torque to automated machines that rely on precision velocity and position loops, such as packaging stations or small transfer modules. It is well suited for repeated starts, stops, and short indexing moves where quick response is required. By combining a low-inertia rotor with electronic commutation, the motor supports rapid acceleration and tight settling times that are important in industrial automation. Those traits help the axis follow command changes with less lag during cyclic motion.

With a frame classified as NEMA Size 34, the motor bolts directly to standard 86 mm mounting patterns. On a 240 VAC bus, the winding can withstand a continuous stall current of 11.0 ARMS, indicating the thermal limit for static torque production without exceeding temperature ratings. Position feedback is supplied by a resolver, whose analog sine-cosine signals remain reliable at high temperatures and in electrically noisy environments. Power and feedback lines exit as flying leads with MS connectors, which helps when the drive cabinet is mounted some distance from the axis. Electromagnetic volume is extended by a stack length multiple of 3, so the stator delivers greater torque per frame than shorter versions in the same motor line. This arrangement supports closed-loop motion on compact axes that need both stable feedback and flexible cable routing.

Application-specific protection is provided through a built-in shaft seal and PTC thermistor. The seal helps block lubricant ingress, while the thermistor allows the drive to react if winding temperature rises too far. Output torque reaches the load through a round shaft that suits clamp or collet couplings when keyed interfaces are not required. The sealed shaft end and integrated temperature sensing support compact servo axes that need basic contamination control and winding protection without additional external devices.
